One-Liners - Get AWS AZ Counts

OK, so not truly a one-liner, but a nice quick-n-dirty way to get a count of all active AZs for each region for your AWS account. echo -e "$(tput bold)Region | # AZs$(tput sgr0)" for region in $(aws ec2 describe-regions | jq -r '.Regions[].RegionName'); do num_azs=$(aws ec2 describe-availability-zones --region ${region} | jq -r '.AvailabilityZones | length') printf '%-15s | %5s\n' ${region} ${num_azs} done This requires jq and the AWS CLI to be installed.

Getting the AWS Big Data Certification

“Why am I so nervous? I haven’t felt like this since… I took the first one.” After five AWS exams (particularly the two pro exams) and a handful of other certification exams, I didn’t really expect to be nervous taking this exam. Oddly enough, this is exactly how I felt going in, during, and in that inexorable “moment” of time between clicking the Submit Exam button and actually seeing the result on the page.

The Path to All Five AWS Certifications

TL;DR This is not a brain dump or a “how-to-pass exam X” post. There are plenty of those elsewhere already. A little over a year ago (last August, to be exact), I unknowingly forked my career path. You may be asking how is that I came to cause such a major divergence while yet remaining unaware as to the fact that I had done so. The answer is both very simple and quite complicated: I got my first AWS certification.

Hugo: Here We Go!

Since I moved back in April, my server has been offline, and with it my old Wordpress-based blog. With my new home, there isn’t really anywhere convenient to run a noisy 1U server blade. This got me thinking about whether or not the server was really essential – of course I still wanted to host my blog somewhere, as well as some other services that I really like having hosted in-house: my own personal Seafile server and email among them.
